Abstract (en)
[origin: EP0989657A2] The present invention is related to an improvement of heat dissipation of the coil-end portions of a stator. The coil-end portions 54 and 55 are disposed around cooling fans 33 and 34 closely, and outer coil ends of the coil-end portions are disposed to be close to the frames 11 and 12 via insulating layers 10a. The coil ends are spaced apart from one another like a cluster except the base portions, and the resistance of cooling air draft inside the coil-end portions is lower than that around the coil-end portions. Therefore, the cooling air mainly passes through the inside of the coil-end portions 54 and 55 so that most of the coil ends can be cooled, thereby providing a high heat dissipation. <IMAGE>
